able bracket on the part f, an adjusting screw 25 is provided, which is mounted in a bearing 26 on the bracket and extends through a nut 27 secured to the part l so that, on turning the screw, the part 4 can be adjusted. On the fixed bracket 17 .is a screw 28, which is arranged to bear. against the frame of a locomotive, holding it against longitudinal movement after adjustment. On thevertical bracket is a screw 29 adapted to a flanged bushing 80. which rests in a curved recess 31 in the bracket. This screw also acts to hold the other frame in proper alignment longitudinally. The screw, with the bushing, can be bodily removed from the bracket, if desired.

In assembling locomotive frames by the use of our improved jig, the two saddle structures are moved longitudinally so that two of the axle box openings in the frame will align with the brackets of the saddle After they are in proper position, they are secured to the foundation plate. The side frame a of the locomotive is mounted on the fixed bracket 17, in the present instance, at two of the openings for the axle boxes, and the side frames can be adjusted longitudinally by the screws 28, the heads of which bear against the walls of the openings. The frames can then be clamped to the saddle structure in any manner desired.

After the side frame a is secured in position, the side frame I) is located on the projecting portion of the movable bracket 20, as shown in Fig. 3. Then the spacers c are located on the two frames a and b, as shown in Figs. 1 and 2, so as to space the two frames the proper distance apart. The screws 29 are adjusted so as to bring the frame 7) in proper alignment with the frame a so that the openings in the frames will be directly opposite each other. After the side frame Z) is properly aligned, it is secured in position in any suitable manner. The permanent spacing members are placed in position and the saddle structure and other parts are assembled on the two side frames.

hen an of the parts have been assembled and it is desired to remove the assembled locomotive frame from the jig, then the part 4 of each saddle structure is moved towards its corresponding part 3 by the screw 14:, as shown in Fig. 7. The frame, in the meantime, has been raised by suitable mechanism so that the lips on the two bracketc will be clear of the frame. Then the movable bracket 20 is retracted by its screw 25 and when it is completely retracted, as in Fig. 8, theassembled frame is moved laterally so as to clear the fixed bracket 17, after which the entire frame. can be raised clear of the jig without removing the pedestal caps of the frame.

We claim:

1. The combination in a jig, of a foundation plate; a twopart. saddle structure mounted thereon, one part being fixed and the other movable towards and from the fixed part. i

2. The combination in a jig, of a foundation plate; a two-part saddle structure mounted thereon; and a bracketon each part, one part being adjustable in respect to the other and one of the brackets being adjustable.

3. The combination in a jig for assembling locomotive and like frames, of a foundation plate; a saddle structure mounted thereon, one part of the saddle structure being fixed and the other part being adjustable towards and from the fixed part; a fixed bracket on the fixed part; and an adjustable bracket on the movable part, whereby the bracket can be retracted when it is desired to remove an assembled frame from the jig.

4. The combination in a jig, of a foundation plate; saddle structures adjustably mounted on said foundation plate, each saddle structure being made in two parts, one of said parts having a. base and the other part being mounted on the base and adjustable towards and from the upper portion of the upper part; a screw for adjusting said movable part; a fixed bracket on one of said parts; and a retractable bracket on the other part.

5. The combination in a jig, of a foundation plate having two longitudinal grooves therein; two saddle structures mountedon. said foundation plate, one part of each structure having a base provided with ribs, which extend into the grooves in the foundation plate; a fixed bracket on said part of the saddle structure; a movable part adapted to ways on the base of the fixed part of the saddle; a screw for adjusting the-said parts towards and from the fixed part; a retractable bracket on the movable part; and a screw for retracting the bracket so as to allow for the removal of the assembled frame.

6. The combinationin a jig, of a foundaion plate; longitudinal grooves therein; a two-part saddle mounted on the foundation plate, one of said parts having a base; ribs on the base adapted to the grooves in the mounted on the foundation plate, one of said parts being fixed as regards lateral movement and having a base, the other part being movably mounted ,on said base; a screw for adjusting the movable part; a fixed bracket on the fixed part of the saddle structure; a retractable bracket on the movable part; a screw on the fixed bracket bearv ing against the frame, the removable bracket having a slot therein; a flanged bushing 10 adapted to the: slot; and a screw mounted in the bushing and bearing against the frame JOHN P.
